Use the following information to answer the next question. Diagram I, below, shows selected magnetic field lines between opposite poles, point P, and an arrow representing the magnetic field strength at point P. Diagram I S N Diagram II shows the same magnetic field, the same point, P, a current-carrying wire oriented perpendicular to the magnetic field, and the direction of the electron flow in the current-carrying wire. Diagram II P. S N X Current- carrying wire X Represents electron flow directed into the page 21. Which of the following diagrams, drawn to the same scale as Diagram I above, represents the net magnetic field strength at point P in Diagram II? A. B. C. D
